Android ListView中的ImageButton会导致问题

我对Android开发相对较新，遇到了以下问题： 我有一个带有相应ArrayAdapter的ListView，它提供简单的项目视图。项目视图以简单的RelatveLayout方式构造，如果使用OnItemClickListener和OnItemLongClickListener的回调方法单击或长按，则会显示一些行为。到目前为止，这一切都很好。但是，如果我使用相应的onClick回调将ImageButton添加到项目视图中，那么项目视图本身上的原始侦听器方法将不再工作。也无法再选择ListView中的项目。为什么?

我不知道这是否有用

ImageView yourImg=(ImageView).findViewById(R.id.icon);
yourImg.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
    // things you want to do 
  }
});

使用

希望它能有所帮助

原因可能有数千个，但没有一个与您的问题相关。你应该包括你的代码，以便我们可以知道你做错了什么。可能重复的Thx链接：就是这样。如果我将android:genderantfocusability=blocksDescendants添加到RelativeLayout中，它会起作用。我没有尝试你的建议，但是我认为，它也不起作用，因为这是一个焦点问题：在项目视图的布局中添加以下属性可以解决这个问题：android:genderantfocusability=blocksDescendants就是这样，thx！项目的包含布局上的第一个属性已经足够了，但是。@Andy您好，第二个属性不是必需的。我很高兴这有帮助：

android:descendantFocusability="blocksDescendants"
android:focusable="false"
